Slipping on the Floors

Now that the weather is getting cooler, I'm trying to figure out what socks to put on my DS to help with slipping on the floor. He's 15 months so this is the first winter he's walking around and we have cold hardwood floors. What are the best type of grippy socks you use?

Also, he was wearing feetie pajamas (carters) last night and when he tried to walk around, he was slipping around like crazy. Has anyone else noticed that the feetie pajamas are slippery too?

Thanks!

Buy puffy paint!! The ones they sell at craft stores. Draw lines, dots, or designs and let dry for 24-48 hours!!
